“Sin is sin?” – The most misleading line of our time

By Fr Robert Christo

In a world where everything seems blurred, one phrase keeps echoing: “sin is sin – big sin? small sin?  same sin .” It sounds simple, even fair. But it is deeply misleading and pastorally dangerous. The Catholic tradition, rooted in Scripture, reason, and lived experience, teaches something far more nuanced and life-giving.

Q: Is “sin is sin”? Is stealing milk the same as mass murder?
No. Sin means “missing the mark,” but not every miss is equal. Taking milk from the fridge without permission is wrong; murder is radically evil. Both miss the mark, but not with the same gravity or consequence.
Scripture is clear: 1 John 5:16–17 speaks of sin that leads to death and sin that does not. The Church calls these mortal and venial sins. St. Augustine of Hippo reminds us: all sin wounds, but not all sin kills.

Q: What is venial sin?
Venial sin weakens love; it does not destroy it. Some call it “small sin,” but small does not mean harmless. Gossip, impatience, cutting corners, making excuses, little lies – these dull the soul. You are still connected to God, but the connection weakens.

Scripture reference?
Caribbean image: like a galvanize roof slowly rusting. It does not fall overnight, but neglect will bring collapse.
Venial sin is forgiven through prayer, charity, and especially the Eucharist – the “I confess” at Mass and worthy Communion cleanse and strengthen the soul.

Q: What is mortal sin?
Mortal sin is a rupture  –  not a crack, but a break. It is spiritual death.
Three conditions must be present:
• Grave matter
• Full knowledge
• Deliberate consent

If one is missing, the sin is not mortal.
Luke 12:47 reminds us that knowing and still refusing carries greater responsibility. Mortal sin creates an inner tomb; and God, who is Life, does not dwell in death.

It is forgiven in the Sacrament of Reconciliation with true contrition, confession, penance, and a firm purpose of amendment.
Local example: if you break your neighbour’s window pane, forgiveness does not cancel responsibility –  you still repair or replace it.

Q: What if I didn’t know?
Knowledge matters. Without it, culpability is reduced. But we are not meant to remain ignorant. God has placed a moral compass within us.
Ezekiel speaks of a new heart –  the natural law written within, irrespective of beliefs.
St. John Henry Newman says conscience is the voice of God within –  but it must be formed even for non- believers.
A compass works only if it is aligned. If the magnet is off, the direction is distorted. So too with conscience. So it is not always wise to follow your conscience unless it is formed.

Q: How do we form our conscience?
Through Scripture, Church teaching, prayer, good guidance, spiritual direction and honest self-examination. Not every feeling and emotion is truth. Conscience must be trained, not just followed.

Q: Why do Adam and Eve still matter?
Because they show the pattern of every sin.
In Genesis 3, they had communion, abundance, divine intimacy – yet chose mistrust and greed.
We do the same.
Imagine you are on an all-inclusive cruise, but unknowingly you lock yourself in the cabin eating crix and cheese. The feast is there, already paid for but you settle for scraps.
St. Irenaeus: humanity turns from fullness to emptiness and pain.

Q: What is the “mystery of evil”?
That we choose less when there is more, it is not just ignorance; it is distorted desire. Judas walked closely and was at the table with Jesus and handed him over to his enemies. So close yet so far. Peter fell too, but repented. Some of them live in us.

Q: What is the biggest problem today?
The loss of the sense of sin.
Pope Pius XII warned that this is the greatest sin of the age. When sin is no longer named, it is no longer resisted. Then it becomes normal – so sad.

Q: What did Jesus, the deliverer, come to do?
Not manage sin but remove it at the root, not just the symptoms.
John 1:29 – the Lamb of God takes away the sin (not only sins) of the world.
From Passover to the Last Supper to the Eucharist, God keeps inviting us back to the feast –  a full, eternal, all-inclusive life with Him.

Q: Where do we receive forgiveness?
Venial sins: prayer, charity, Eucharist, especially at the penitential rite and Reception of communion.
Mortal sins: Sacrament of Reconciliation (John 20:23).
Confession not only forgives; it gives grace to strengthen us to resist future temptation.

Q: Why no loopholes or excuses?
Because sin is relational, not just legal.
Matthew 12:37 – our words will judge us.
One of the greatest dangers is lying to ourselves about ourselves. Don’t wait for the last judgement; it takes place every day.

Q: What daily practices help?
• Nightly examination of conscience – don’t wait for the last judgment
• Reconcile quickly so you can worthily go to the altar
• Avoid occasions of sin
• Regular confession
• Worthy, frequent Communion

Let every night be a mini-judgment, every morning a fresh start.

Q: “Better to lose a limb than sin” – what does that mean?
Mark 9:43–45 uses strong language to show urgency.
Better wounded into eternal life than whole into eternal loss. Nothing is worth losing your soul.

Q: If there is no sin in heaven, what happens to venial and mortal sin after death?
Mortal sin, unrepentant, separates from God forevermore.
Venial sin is purified by grace now, and if needed, after death in purgatory (see 2 Maccabees 12).
Heaven admits no sin – only the fully healed.

Q: Final word?
Sin isolates; grace restores.
Romans 5:20 – where sin increased, grace abounded more.

Stop settling for less: crix and cheese.
The Eucharist is the premium all-inclusive.
The table is set.

Step out of the cabin and take your place at the all-inclusive feast – a rehearsal for that eternal banquet where there is no sin any longer.
